Abstract (en)

An image processing device includes an acquiring unit that acquires a captured image; an extracting unit that extracts first feature data and second feature data of a first user included in the image; a calculating unit that calculates a first authentication decision value, which indicates a probability that the first feature data of the first user resembles first feature data of a second user; and an authenticating unit that authenticates the first user by using the first feature data or both the first feature data and the second feature data according to the first authentication decision value.
